I will never forget my teacher Miss Lee, who is my English teacher when I was in high school. Miss
Lee was younger, pretty and kind-hearted. That is hard for me to describe how she was like. However,
she really had her own personalities. She let us elect our monitor and decided where to go for an outing.
Besides, she liked to have us solving (解决) problems by our own. And we made a great progress
quickly in our studies. It wasn't long since most of us behaved properly because we found her a good
friend who we could depend.
